Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a radiation-proof neck brace for cervical spine fractures. Background Technology

[0002] The cervical spine is a relatively fragile organ in the human body. In daily life and sports, due to insufficient protection of the cervical spine, the possibility of cervical spine injury is greatly increased. In severe cases, cervical spine fracture may occur. Patients with fractures need to wear a cervical collar to help with cervical spine rehabilitation.

[0003] During the rehabilitation process, if it is necessary to understand the condition of the cervical spine, X-ray imaging of the cervical spine is required. Taking advantage of the attenuation law of X-rays in matter and the characteristic that X-rays can cause certain substances to fluoresce and photochemically react, the X-rays are passed through the workpiece being examined and irradiated onto the X-ray film to expose the film. After processing in a darkroom, a photographic film reflecting the internal condition of the workpiece is obtained. This film is then analyzed under a strong light to determine the internal quality of the workpiece being examined.

[0004] When undergoing cervical spine X-ray imaging, patients lie on the examination bed wearing lead aprons. However, lead aprons only provide radiation protection for the patient's body, but the face is often overlooked, making it vulnerable to X-ray damage. Therefore, it is essential to design a neck brace that can provide radiation protection for the face during X-ray imaging. Utility Model Content

[0005] To address the technical problem of existing technologies that lack facial radiation protection during X-ray imaging after cervical spine fractures, this utility model provides a radiation-proof neck brace for cervical spine fractures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A radiation-proof neck brace for cervical spine fractures includes a neck brace body that can be fixed to the user's neck, and a protective face shield that is detachably connected to the neck brace body and can cover the user's face. The protective face shield includes a plurality of spaced-apart arched supports, a connecting mechanism that connects the plurality of arched supports and allows the arched supports to telescopically move along the arrangement direction, and a lead cloth cover that is detachably connected to the outer surface of the arched supports and can cover the arched supports and the connecting mechanism. The arched supports include a first support body and a second support body connected at one end by a pivot. Both the first support body and the second support body can rotate around the pivot, and the rotating second support body can be folded inside the first support body. The lead cloth cover has a plurality of through holes communicating with the interior of the arched supports, and each through hole is connected to a lead cloth cover for controlling the opening or closing of the through hole.

[0008] Furthermore, the outer walls of the two arched supports at the ends are provided with several locking holes, and the inner surface of the lead cloth cover is provided with several locking pins that can engage with the locking holes, and the positions of the locking pins correspond one-to-one with the locking holes.

[0009] Furthermore, the outer surfaces of both the first support and the second support are provided with a number of spaced-apart card interfaces, and the inner surface of the lead cloth cover is provided with a number of buckles that can be engaged one-to-one with the card interfaces.

[0010] Furthermore, both the first support body and the second support body have telescopic support rods connected to their lower ends. Each telescopic support rod includes a first rod body with one end connected to the lower end face of the first support body or the second support body, and a second rod body connecting the other end of the first rod body to the second support body. The end face of the second rod body away from the first support body or the second support body is covered with a silicone layer.

[0011] Furthermore, the connecting mechanism includes two spaced-apart first telescopic members and a plurality of second telescopic members connected between the two first telescopic members. The first telescopic member is composed of two two-hole connecting rods that are cross-connected at one end, and the cross-connection of the two two-hole connecting rods is also connected to the first support body at the end. The second telescopic member is composed of two three-hole connecting rods that are cross-connected in the middle, and the cross-connection of the two three-hole connecting rods is also connected to the first support body at the corresponding position. The two shaft holes on the same side of the three-hole connecting rods can be connected to the shaft holes on the two-hole connecting rods or the three-hole connecting rods at the corresponding positions.

[0012] Furthermore, the connecting mechanism includes a plurality of telescopic connecting rods disposed between two adjacent first supports. Each telescopic connecting rod includes a third rod and a fourth rod, one end of which is respectively connected to the side wall of the corresponding first support. The other end of the third rod is sleeved in the fourth rod, and the third rod can reciprocate within the fourth rod.

[0013] Furthermore, the neck brace body includes a front piece with an opening and a rear piece that can be connected to the front piece via a fixing strap. The front piece has several connecting buckles distributed around the outer periphery of the front piece, and the rear piece also has connecting buckles distributed on both sides near the edge of the rear piece.

[0014] Furthermore, the edge of the lead cloth cover is sewn to the lead cloth cover body, and the remaining edge is attached to the lead cloth cover body with Velcro.

[0015] In summary, the beneficial effects of this utility model are as follows: 1. When the neck support body is fixed behind the neck and the user is lying on the examination bed for examination, the protective mask can cover the user's face. The arched support provides support above the user's face, allowing the lead cloth cover to cover the face for radiation protection, while maintaining a certain distance from the face so as not to affect the user's normal breathing. This protective mask covers and protects the face, eyes, and other organs, blocking X-rays from damaging the face. 2. The protective mask is connected to the lead cloth cover via a hook and corresponding buckle, making assembly and disassembly very convenient and quick. The neck support body, after removing the protective mask, can be used as a regular neck fixation device, while the removed protective mask can be reused, saving resources. 3. The arched support can be adjusted in length and height via a telescopic support rod, making it suitable for a wider range of users' faces. Fourth, several arched supports can converge into a contracted state, while the second support can be folded and stored inside the first support. The soft lead cloth cover can also be folded and stored, and the entire protective mask can be folded and stored, saving space. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further illustrated below with reference to specific figures.

[0022] Please see Figure 1This utility model provides a radiation-proof neck brace for cervical spine fractures, including a neck brace body 100 that can be fixed to the user's neck, and a protective face shield 200 detachably connected to the neck brace body 100 and capable of covering the user's face. The protective face shield 200 includes a plurality of spaced-apart arched supports 210, a connecting mechanism 220 connecting the plurality of arched supports 210 and enabling the arched supports 210 to extend and retract along the arrangement direction, and a lead cloth cover 230 detachably connected to the outer surface of the arched supports 210 and capable of covering the arched supports 210 and the connecting mechanism 220. The arched supports 210 include a first support body 212 and a second support body 213 connected at one end by a pivot 211. Both the first support body 212 and the second support body 213 can rotate around the pivot 211. Please refer to [link to relevant documentation]. Figure 4 The rotating second support 213 can be folded inside the first support 212. The lead cloth cover 230 has several through holes 111 that communicate with the interior of the arched support 210. Each through hole 111 is connected to a lead cloth cover 231 for controlling the opening or closing of the through hole 111. The protective mask 200 can be detached from the neck brace body 100. After fixing the neck brace body 100 behind the neck, the patient or user lies on the examination bed, and then the protective mask 200 is connected to the neck brace body 100. Several arched supports 210 that can be extended and moved are then unfolded, placing the patient's face inside the arched supports 210. The arched supports 210 have an arched structure and support the connected lead cloth cover 230, which covers the user's face. Due to the support of the arched supports 210, there is a certain space between the lead cloth cover 230 and the user, which does not affect the user's normal breathing. When radiographing the neck, the lead cloth cover 230 can block X-rays, protecting the entire user's face. Moreover, when not radiographing, the two through-holes 111 provide a visible field of view, facilitating observation of the inside and outside of the protective mask 200. The several arched supports 210 can retract and close together, and can also be extended and unfolded, adapting to more users. Furthermore, each of the second supports 213 can be folded inside the first support 212, and the lead cloth cover 230 is also made of soft material that can be folded, so that the protective mask 200 has the function of saving storage space.

[0023] Please see Figure 2The neck support body 100 includes a front piece 110 with an opening 111 and a rear piece 120 that can be connected to the front piece 110 via a fixing strap 130. The front piece 110 has several connecting buckles 140 distributed around its outer periphery, and the rear piece 120 also has connecting buckles 140 distributed near its edge on both sides. The lead cloth cover 230 has several soft hook sleeves on its edge, which can be hooked one by one to the connecting buckles 140. After the user lies on the examination bed, the protective mask 200 covers the face for protection. Since the hooks of the front piece 110 are distributed near the chin rest 150, when the hook sleeves are connected to the connecting buckles 140, the lead cloth cover 230 can extend to protect the user's chin. Moreover, once the lead cloth cover 230 is securely connected to the neck support body 100, even if the user moves, there is no need to worry about the lead cloth cover 230 shifting, thus always protecting the face. Furthermore, disassembly is very simple and convenient.

[0024] The edge of the lead cloth cover 231 is sewn to the lead cloth cover 230, and the remaining edge is attached to the lead cloth cover 230 with Velcro, making it very convenient and quick to close or open the through opening 111.

[0025] Please see Figure 3 The outer walls of the two arched supports 210 at the ends are provided with several locking holes 214. The inner surface of the lead cloth cover 230 is provided with several locking pins that can engage with the locking holes 214. The locking pins are distributed in multiple rows along the length of the lead cloth cover 230, with two rows preferably located close to the edge of the lead cloth cover 230. The positions of the locking pins correspond one-to-one with the locking holes 214. When the arched supports 210 are extended or retracted, the soft lead cloth cover 230 can be stably fixed on the arched supports 210 by corresponding locking pins engaging with the locking holes 214.

[0026] The outer surfaces of both the first support 212 and the second support 213 are provided with several spaced-apart snap-fit ​​interfaces 215, and the inner surface of the lead cloth cover 230 is provided with several snaps that can be snapped into place one by one with the snap-fit ​​interfaces 215. The snap-fit ​​lead cloth cover 230 is easy and quick to install and remove, and it can also make the lead cloth cover 230 more secure, so that it can always cover the face for radiation protection.

[0027] Both the first support body 212 and the second support body 213 have telescopic support rods 300 connected to their lower ends. Each telescopic support rod 300 includes a first rod 310 with one end connected to the lower end face of either the first support body 212 or the second support body 213, and a second rod 320 connecting the other end of the first rod 310. The end face of the second rod 320 away from the first support body 212 or the second support body 213 is covered with a silicone layer (not shown in the figure). When the user lies on the examination bed for examination, the end face of the second support body 213 with the silicone layer contacts the examination bed, increasing stability and reducing displacement. Furthermore, the height of the arched support 210 above the face can be adjusted according to the different head shapes of different users; for example, the required support height can be adjusted for children or adults.

[0028] The connecting mechanism 220 includes two spaced-apart first telescopic members and several second telescopic members connected between the two first telescopic members. Each first telescopic member consists of two two-hole connecting rods 221 with one end crossed and pivotally connected, and the intersection of the two two-hole connecting rods 221 is also pivotally connected to the first support body 212 at the end. Each second telescopic member consists of two three-hole connecting rods 222 with one end crossed and pivotally connected, and the intersection of the two three-hole connecting rods 222 is also pivotally connected to the first support body 212 at the corresponding position. Two shaft holes on the same side of the three-hole connecting rods 222 can be pivotally connected to the shaft holes on the corresponding two-hole connecting rods 221 or three-hole connecting rods 222. The several spaced-apart arched supports 210 are telescopically adjustable, meaning they can be adjusted to fit the length of the face protection, making them more versatile and suitable for more users. Furthermore, these telescopically adjustable arched supports 210 save storage space when retracted.

[0029] In another embodiment, the connecting mechanism 220 includes a plurality of telescopic connecting rods disposed between two adjacent first supports 212. Each telescopic connecting rod includes a third rod and a fourth rod, one end of which is respectively connected to the side wall of the corresponding first support 212. The other end of the third rod is sleeved within the fourth rod, and the third rod can reciprocate within the fourth rod. Telescopic movement between adjacent first supports 212 via the telescopic rods also enables the arched support 210 to be adjusted in length direction.

[0030] This neck brace has the following features: 1. The neck brace body 100 is fixed behind the neck. When the user lies on the examination bed for examination, the protective mask 200 covers the user's face, and the arched support 210 provides support above the user's face. This allows the lead cloth cover 230 to cover the face for radiation protection, while maintaining a certain distance from the face to avoid affecting the user's normal breathing. This protective mask 200 covers and protects the face, eyes, and other organs, blocking X-rays from damaging the face. 2. The protective mask 200 is connected to the corresponding connecting buckle 140 via a hook on the lead cloth cover 230, making assembly and disassembly very convenient and quick.
